Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive a communication from a second UE. The first UE may select an index that represents multiple control bits associated with the communication. The first UE may transmit an indication of the index in a portion of a physical sidelink feedback channel (PSFCH) resource pool that is selected based at least in part on the index. Numerous other aspects are described.

Abstract: CG-based sidelink beamforming alignment is disclosed. The initiator UE may receive, from a base station, a CG indicating one or more CG resources for a beamforming alignment procedure. The initiator UE may transmit, to at least one responder UE via one or more Tx beams on the one or more CG resources, beam-sweeping SCI for the beamforming alignment procedure. The beam-sweeping SCI may include at least one of: a Tx beam index, a time period to monitor for beam-feedback SCI, or a time window including CG occasions for a same beam transmission of ACK SCI. The initiator UE may monitor, over the time period, for beam-feedback SCI from the at least one responder UE. The initiator UE may receive, from the at least one responder UE, the beam-feedback SCI within the time period.

Abstract: Aspects presented herein may enable a base station to configure constraints on one or more transmission directions of a UE to reduce interference between UEs. In one aspect, a UE receives, from a base station, a grant for time-frequency resources for transmitting to a second UE, the grant including information indicating at least one of a first subset of beams of a set of beams for which the grant applies or a second subset of beams of the set of beams for which the grant applies with a constrained transmission power. The UE transmits, to the second UE, a PSSCH through at least one beam of the first subset of beams based on the received grant, or through at least one beam of the second subset of beams with the constrained transmission power based on the received grant.

Abstract: Wireless communications systems and methods related to COT aware autonomous sidelink sensing are provided. A first user equipment (UE) selects at least a first resource from available resources in a sidelink resource pool within a shared radio frequency band. The selecting the first resource may be based on a channel-access gap preceding each resource of the available resources. The first UE further transmits, to a second UE using the selected first resource, one or more data blocks for a sidelink transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.

Abstract: Wireless communications systems and methods related to frequency resource reservation for sidelink communication over a shared radio frequency band are provided. A first user equipment (UE) senses in a sidelink resource pool within a shared radio frequency band. The first UE reserves, based on the sensing, a frequency resource of the sidelink resource pool within an instance of a variable time range. The first UE performs, in the shared radio frequency band, one or more listen-before-talks (LBTs). The first UE transmits, to a second UE based on the one or more LBTs, a sidelink transmission using the frequency resource within the instance of the variable time range.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first UE may receive, from a second UE, resource reserving sidelink control information that indicates a transmit beam of the second UE and a sidelink resource of the second UE. The first UE may transmit data on the sidelink resource of the second UE using a transmit beam of the first UE that does not spatially overlap with the transmit beam of the second UE. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to power saving over a forward link of a star topology of user equipment (UE) are provided. In some aspects, a first UE may monitor the forward link connecting a second UE to the first UE for a control message transmitted by the second UE to the first UE. The first UE may then establish an operational mode based on the result of the monitoring for the control message, such as but not limited to a power saving mode or an active mode.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may perform a listen before talk (LBT) procedure on a channel bandwidth using an energy detection (ED) threshold. The ED threshold being associated with a transmission bandwidth that is narrower than the channel bandwidth. The wireless device may also, responsive to a successful LBT procedure, transmit on the transmission bandwidth according to a frequency hopping pattern during a first channel occupancy time (COT). The frequency hopping pattern comprises a first resource allocation and a second resource allocation different from the first resource allocation.
